Freezes when editing Markdown with embedded JavaScript

[LukasKnuth]

Summary

While editing a fenced JavaScript code-snippet in a Markdown file, the Editor freezes up. It does not react to anything and I have to kill -9 it in order to close the process.

Reproduction Steps

```javascript
 {
arg
}

```

NOTE The empty line at the end of the code-block is important!

I tried this:

1. hx minimal_error.md
2. Navigate the cursor somehow onto the closing curly-bracket
3. The editor freezes while hovering the closing curly-bracket

NOTE: I can navigate around that closing curly-bracket as much as I like. It does not matter if I navigate onto it from the top using jjj or from the bottom using gekk. As long as I don't hover the bracket, the editor behaves as expected.

I expected this to happen:

The editor does not freeze and

Instead, this happened:

The editor freezes and must be killed using kill -9

Helix log

I have killed the editor about 30 times now trying to get a minimum reproducible snippet. All I see in the log from that time are the errors listed below, there is no additional information.

know issue withi the last release caused by a bug in an old treesitter version, this has been fixed on master for a long time

[LukasKnuth]

So the fix is to build the editor from source?

Any plans for a new release with the fixes?
